TwlN ENvELoP.

SPECIFICATION lforming part of Letters Patent No. 754,373, dated March 8, 1904. Application filed April 2l, 1902. Renewed September 9, 1903. Serial No. 172,525. (No model.)

To all whom t may concern,.-

Be it known that I, ARCHER G. J oNEs, a citizen of the United States, residing at Riclimond, in the county of Henrico and State of Virginia, have invented certain new and useful Improvements in Twin Envelops, of which the following is a speciication.

The accompanying drawings illustrate my improvement in envelops of the twin type designed for church collections; and my said improvement resides in the precise provision shown whereby the sealed twin envelop is rendered separable, as will be set out in the claim appended hereto.

In the drawings, Figure 1 shows the blank from which the twin envelop is formed as it is provided with my improvement. Fig. 2 shows the back of the formed twin envelop with the sealing-laps open. Fig. 3 shows the same with the sealing-laps closed. Fig. i shows the front ofthe envelop. Fig. shows the blank with a slightly-modified form of my improvement.

The blank is preferably of square form, l being the back fold, the frontQ having the side edge gummed laps 3 3 and the gummed sealinglaps 4 4. meeting at a point 5 mediately of the length of the twin envelop, at which point the separation of the twin envelop is made. It is the means whereby this separation is effected, leaving each envelop sealed, wherein my improvement resides. Looking at Fig. 1 is seen two gummed lines or strips 6 6 standing parallel across the width on eaoh side of the point 5, at which the sealing-laps 4 4: meet, so as to leave an ungummed narrow tear-space 7,1eading from the meeting-point 5 of the sealing-laps between the gummed lines or strips 6 6 on the inner sides of both the front and back. These separated gummed lines or strips are shown on the inner side of the front; but

obviously they may be on the inner side of the back fold or one gummed line or strip on the front and one gummed line or strip on the back fold, as in Fig. 5, so that when the back fold is laid upon the front and sealed, the tearspace will be between the lines or strips of gum. By this arrangement of the gummed lines or strips 6 6 and the ungummed space between themthe twin envelops can be separated by tearing them in the tear-space 7 of both the back fold and the front between the gummed lines or strips. This arrangement of the gummed lines or strips in pairs not only seals the joining of the twin envelops, but forms walls or guards along the tear-space of the envelope to prevent the deection of the tear into either of the pockets or envelope.

The gummed lines or strips can be applied as the blank is formed or afterward and moistened to join the back fold and front. Obviously the twin envelops can be joined end for ends with the tear-space flanked, as described,

with parallel lines or strips of gum.

I claim- A twin envelop formed with front and back folds, the front fold having end and side gummed laps, and a pair of gummed lines arranged to flank an ungummed tear-space and to close the joining sides of the pair of envelops at the opposite sides of the tear-space, the pair of gummed lines terminating at the folding -lines of said end sealinglaps and anking their meeting-point at said lines for the purpose stated.

In testimony whereof I afliX my signature in presence .of two witnesses.

ARCHER G. JONES.
